## FAQs

### Is this Firefox browser mockup generator free?

Yes — completely free, no signup, no watermarks. Wrap unlimited product screenshots in a realistic Firefox window for launches, landing pages, and decks. Everything renders in your browser; nothing is uploaded to AdSights.

### What Firefox details does the frame include?

The Firefox preset renders the rounded tab shapes, the unified address bar with the shield and lock icons, the back/forward/reload/home controls, and the toolbar menu — matching the current Firefox desktop chrome in both light and dark themes.

### Can I customize the background and theme?

Yes. Add a custom gradient background (or pick a preset swatch), toggle the drop shadow, edit the address-bar URL, and switch between light and dark Firefox chrome so the frame matches your screenshot.

### What export formats are supported?

Both PNG and WebP, captured at retina (2×) density via html2canvas — PNG for maximum compatibility, WebP for smaller files at comparable quality. Uploaded source screenshots can be PNG, JPG, or WebP.

### How is this different from the umbrella Browser Mockup Generator?

This page boots straight into the Firefox frame with Firefox-specific copy, FAQs, and a shareable URL. The umbrella [Browser Mockup Generator](/resources/tools/generators/browser-mockup-generator) is the right entry when you want Firefox alongside Chrome and Safari in one session.
